Robot lawn mowers are outdoor smart devices that simplify one of the toughest house chores. Whether you're fortunate enough to have a 1-acre lawn, or you just want a robot mower that's rated for such a large yard so you're sure that it can handle yours, there are several options out there. You should be ready for the investment though, as these devices won't come cheap.

For this roundup, we've gathered seven of the best robot lawn mowers that can trim over an acre daily, featuring popular manufacturers, a brand crossing over from robot vacuums, and some up-and-coming names in the space.

In addition to their daily coverage of more than 1 acre, the robot lawn mowers that we've chosen also come with several helpful features that make them worth buying. We consulted professional reviews for insights into the capabilities of these machines, most of which may be purchased on Amazon.

The Husqvarna 440iQ can cover an area of more than 1 acre within 24 hours. The brand's Exact Positioning Operating System (EPOS) enables location data that's accurate down to the centimeter, with radar technology to navigate around objects on your lawn. Direct sunlight, dust, and darkness will affect cameras but not radar's radio waves, which gives this Husqvarna robot lawn mower an advantage, according to Robot Mower Lab.

There's no need for expert-level technical knowledge with this Husqvarna robot lawn mower, as installation and operation are all carried out through its smartphone app. This is where you can change the machine's cutting height from 1 inch to 4 inches, adjust its schedule, set zones to avoid, select its mowing pattern, and more. The machine will have no problem moving up 45% slopes, and it's designed for durability with sturdy bumpers and wheels. Once it's done, you can wash it with your garden hose for easy maintenance. For $4,299, you'll also get free cutting blade replacements for a year.

The Segway Navimow X450, available on Amazon for $2,999, is capable of mowing a 1.5-acre area within a 24-hour period. It's built like a rugged RC truck with a dual suspension system that allows it to easily move through uneven terrain, climb 84% slopes or over objects up to 2.8 inches in height, and cross over potholes as long as 5.9 inches. The machine also has a pair of 180W motors, one for each cutting disc, and a 17-inch cutting width for efficiency. It automatically changes the blades' height to handle different types of grass, and it can shift its schedule when it detects rainy weather through a sensor.

Gadgets & Gravel's review of this Segway robot lawn mower showed that it can move under trees and bushes without losing connection, and described it as a very reliable machine with no issues even after about a month of usage. It uses NRTK navigation so you won't have to set up an antenna, and with the tap of a button on its companion app, the robot lawn mower creates a map of your yard that you can then edit for boundaries and no-go zones. The machine's AI-powered camera recognizes more than 200 objects to avoid them, and you can control it using voice commands through either Amazon's Alexa or Google Home. 

Dreame, a brand that started with stick and robot vacuums, has ventured into robot lawn mowers with the Dreame A3 AWD Pro 5000. This $3,859.99 machine can cover up to 1.2 acres in a span of 24 hours, and with wheels and a suspension system that look like they're from an off-road vehicle, it can climb up 80% slopes, maintain traction over difficult conditions, and travel over obstacles up to 2.2 inches in height. The robot lawn mower has a cutting width of 15.8 inches, with blades that take only seconds to swap, and a noise level of below 65 decibels, so it won't be a disturbance to anyone while it works in the yard.

This Dreame robot lawn mower uses the brand's OmniSense 3.0, which is a combination of LiDAR and AI vision for accurate navigation, obstacle avoidance, and mapping. The machine also has built-in 4G support, which Android Authority highlighted in its review. Your home's Wi-Fi network might not reach all the corners of your yard, and when this robot lawn mower moves into such an area, you'll still be able to control it through the app.

The Mammotion Luba 3 AWD 5000, available on Amazon for $3,299, can comfortably mow 1.25 acres in a day. Trusted Reviews said that it's an excellent machine if your lawn has rough terrain because it can make the necessary adjustments with its all-wheel drive and adaptive suspension system. It can also climb 80% slopes, with a pair of 165W motors each powering a six-blade disc for efficient cutting at heights between 1 inch and 2.7 inches.

This Mammotion robot lawn mower uses NRTK technology, 360-degree LiDAR, and AI vision with two cameras to accurately map your yard and identify objects. The machine plans the best path for cutting grass, and you can define up to 50 zones, including no-go zones. Trusted Reviews said that it's effective at detecting obstacles, and the app is easy to use for arranging mowing schedules, editing maps, and accessing the robot lawn mower's cutting settings.

The Lymow One Plus is $2,799 on Amazon, but PCWorld claims that the robot lawn mower is worth it, starting with a battery that mows 0.57 of an acre per charge. In three cycles per day, the machine can trim 1.73 acres, and it will be able to handle all kinds of terrain as it can climb 100% slopes and go over objects as high as 2.8 inches. Using the Lymow app, you can define up to 80 zones with virtual boundaries, and for each of them, customize schedules and cutting heights from 1.2 inches to 4 inches.

This Lymow robot lawn mower uses an RTK antenna though, which makes setup more complex compared to others using NRTK technology. However, once it's up and running the machine works much faster than the usual pace of robot lawn mowers, and with its dual blades, it has no trouble with taller grass where others with smaller blades may get bogged down. VSLAM, AI vision, and ultrasonic sensors help the robot lawn mower make visual maps and avoid objects on your lawn — plus it mulches as it mows to keep your grass healthy.

The Yarbo Pro is a machine that can mow up to 1.7 acres in a day, over the course of seven runtime and recharge cycles. You need to first properly set up its NRTK, to create a map of your yard with up to 100 mowing zones, but once all that's done, the robot lawn mower's "power is undeniable," according to Tom's Guide. The review said that the machine cuts cleanly and evenly, and that it almost never bumps into anything with its GPS, six HD cameras, and two ultrasonic radars.

The Yarbo Pro is the most expensive robot lawn mower in this article at $5,999 on Amazon, and this is partly because it's a modular machine. You can equip it with attachments to transform it into a leaf blower and a snow blower so that it will be able to work in different seasons, though these are additional purchases. It's capable of moving through all kinds of terrain, and its twin blades are each powered by a 300W motor to handle thick grass at heights of 0.8 of an inch to 4 inches. 

The Goko M6 comes in two versions: a single-battery model for $3,499 that can cover 1.5 acres in 12 hours, and a dual-battery model for $3,899 that can cover 2 acres in the same amount of time. With front-wheel steering, adaptive suspension, and high-traction four-wheel drive, it can move across uneven terrain and head up 90% slopes. Meanwhile, its AI-powered QuadVision technology — named as such because it uses two cameras at the front and a camera at each side for a wider field of view — allows it to recognize and avoid hitting more than 200 objects. You have the option between two blades for the machine — razor disc blades and rotary mulching blades — and according to MrYouWho, swapping them for one another is an easy process.

MrYouWho added that the Goko robot lawn mower gives you complete control over how you want it to manage your yard. Through the app, you'll be able to define up to 250 zones across maps stretching up to 15 acres, change cutting height, speed, and manage mowing schedules. You'll also be able to view live camera feeds through the robot lawn mower using the app, in case you want to visually confirm its progress.

The robot lawn mowers featured in this article are rated for coverage of more than 1 acre per day. Most of them may be purchased on Amazon for wide accessibility, as well as a chance for discounts as these machines are pretty expensive.

Robot lawn mowers aren't popular purchases on Amazon, probably because they're a significant investment that not all families will purchase. Instead of ratings on the platform and customer reviews, we based our selections on feedback from trustworthy websites and channels. If you're seriously considering buying one, we want to make sure that you get a robot lawn mower that's worth it.
